营养治疗是临床综合诊疗的重要组成部分，加强临床营养学教学有助于住院医师提高营养诊疗水平。本文以中南大学湘雅二医院2023年接受规范化培训的437名住院医师为例，阐述了混合式教学方法在住院医师临床营养学教学中的设计和实施过程。通过基础理论知识测试和培训前后各3个月内住院患者24小时内营养风险筛查率、营养评估率等指标比较培训前后住院医师的营养诊疗情况，通过问卷调查了解住院医师的教学满意度。结果显示，培训后住院医师的临床营养学基础理论知识合格率从培训前的18.8%(82 /437)上升至100.0%(437/437)。住院患者的营养风险筛查率(完成营养风险筛查人数/住院患者总人数)从30.5%(9 181/30 103)上升至91.3%(28 329/31 029)，24小时内营养风险筛查率(24小时内完成营养风险筛查人数/住院患者总人数)从20.1%(6 051/30 103)上升至36.8%(11 419/31 029)，营养风险筛查合格率(营养风险筛查合格份数/抽查总份数)从51.2%(4 475/8 740)上升至84.9%(7 420/8 740)，营养评估率(完成营养评估人数/住院患者总人数)从3.2%(968/30 103)上升至9.9%(3 072/31 029)，其差异均具有统计学意义(均 P<0.001)。问卷调查结果显示，住院医师对混合式教学方法满意程度评分为(4.85±0.36)分，对混合式教学提升临床营养诊疗水平的满意度评分为(4.82±0.39)分。混合式教学方法应用于住院医师临床营养学教学有助于其掌握临床营养学知识，有助于其提升临床营养诊疗实践能力，得到了住院医师的认可。

Nutritional therapy is an important component of comprehensive clinical diagnosis and treatment. Strengthening clinical nutrition education can help resident physicians improve their level of nutrition diagnosis and treatment. This study introduced a hybrid teaching method that combines online and offline teaching into the teaching of clinical nutrition for 437 resident physicians, and observed its application effect. For all resident physicians in our hospital in 2023, the basic knowledge classroom of clinical nutrition was set up through online teaching, and combined with offline case-based clinical nutrition diagnosis and treatment teaching classroom as an example, the teaching design and implementation process of blended learning in resident physician clinical nutrition teaching were elaborated. The basic knowledge mastery of resident physicians was compared before and after training through knowledge test. The effectiveness of teaching was evaluated by comparing indicators such as nutritional risk screening rate and 24-hour nutritional risk screening rate to understand the nutritional diagnosis and treatment of resident physicians before and after training. The results showed among the 437 resident physicians who participated in the training, the qualification rate of clinical nutrition basic knowledge significantly improved after training from 18.8% (82/437) to 100.0% (437/437). The nutritional risk screening rate of hospitalized patients increased from 30.5% (9 181/30 103) to 91.3% (28 329/31 029), and the nutritional risk screening rate within 24 hours increased from 20.1% (6 051/30 103) to 36.8% (11 419/31 029). The qualified rate of nutritional risk screening increased from 51.2% (4 475/8 740) to 84.9% (7 420/8 740). The evaluation rate increased from 3.2% (968/30 103) to 9.9% (3 072/31 029), and all differences were statistically significant (all P<0.001).The questionnaire survey results showed that the satisfaction rating of resident physicians with blended learning was (4.85±0.36) points, and the satisfaction rating of blended learning in improving clinical nutrition diagnosis and treatment level was (4.82±0.39) points. It can be seen that the application of blended learning in the clinical nutrition teaching of resident physicians helps them to master clinical nutrition knowledge and improve their practical abilities of clinical nutrition diagnosis and treatment.
